Title: Burst signal transmission radio system
Inventor: MIYAJIMA TAKAHIKO
IPC: H04B7/15
Filed: 1990-04-04
Abstract: PURPOSE:To increase number of branched routes effectively by grouping properly plural routes of a radio station having the plural branched routes using a same frequency band and applying switching control to a time when a signal is sent in the unit of each group by a prescribed method. CONSTITUTION:For example, routes B, D, F are grouped as group 1 and routes C, E are grouped as a group 2, and radio stations A, B, D, F connecting to the routes belonging to the group 1 make transmission/reception for a time T at a time interval 2T0 of t0, t2, t4,..., where T is shorter than the time T0. Moreover, radio stations A,C, E connecting to the routes belonging to the group 2 make transmission/reception for a time T at a time interval 2T0 of t1, t3, t5,.... Thus, signal transmission is implemented without simultaneous transmission/reception between the radio stations belonging to the group 1 and the radio stations belonging to the group 2 to generate lots of route number.

Title: Printer
Inventor: KAWAMURA YOSHIAKI
IPC: G03G21/00
Filed: 1984-05-07
Abstract: PURPOSE:To provide a printer capable of wastelessly displaying its processing capability, by informing the operator of the timing of supplying a paper by manual insertion. CONSTITUTION:In continuous printing, cut sheets are fed from a paper-supplying cassette 4 by one sheet at a time, are printed by a printing part 3, and are outputted into a paper-discharging stacker 7. When supplying the paper by manual insertion, a cut sheet is inserted through a paper-supplying port 5 for manual insertion when a buzzer 9 is operated. Since the printer informs the operator of an optimum timing for manual-insertion paper supply, the operator needs only to operate according to the information without need to use his head. Thus, both the process of continuous printing and the process of manual-insertion printing are collectively controlled by a controlling part 8. Accordingly, for example, even during continuous printing conducted by using papers encased in the paper- supplying cassette, printing for other purpose by manual-insertion paper supply can be inserted without fear of jamming.

Inventor: MATSUDA KOREHITO
IPC: H01L21/30
Filed: 1979-07-17
Abstract: PURPOSE:To detect an intersection with high reliability from a mark detection signal obtained by one beam scanning in a mark detector by detecting all the intersections between the mark detection signals and reference voltage and averaging these data. CONSTITUTION:A mark detection signal 12 is inputted to a comparator 15. A signal is fed to the controller 16 of a beam deflecting D/A converter every time the signal 12 exceeds the reference voltage 13 to latch the input value of the D/A converter. Simultaneously, pulses of number that exceeds the reference voltage 13 by the signal 12 are fed to a counter 18 for counting the pulses. Then, the input values Di of the respective D/A converters and the counted number Ni are applied to an arithmetic unit 19, which calculates the average of D'=(SIGMANiXDi)/SIGMANi (where i=1, 2,...,n). Here, n represents the number of steps of the D/A converter required for scanning the beam. The D' thus obtained is averaged to suppress the adverse effect of the noise to give reliable mark edge position thereto.

Title: Air pole material for molten carbonate fuel cell
Inventor: YAMANAKA ATSUSHI
IPC: H01M4/86
Filed: 1990-04-06
Abstract: PURPOSE:To improve the molten salt resistance of an air pole material and contrive a longer life of a cell by specifying the nickel - manganese composition in a nickel - manganese complex oxide having a spinel type crystal structure. CONSTITUTION:A nickel manganese-complex oxide having a spinel type crystal structure is used as an air pole material for fuel cell. In the formula Ni1-xMn2+xO4, when x is less than 0.4, high electric conductivity is exhibited, but solubility of metal ion to molten salt is undesirably high as the fuel cell air pole material. When x is larger than 0.8, electric conductivity is reduced. Thus, in consideration of molten salt resistance and high temperature electric characteristic, the value of x is 0.4<=x<=0.8. Hence, the elution to the molten carbonate which is an electrolyte is minimized, and a longer life of the cell is contrived.

Abstract: PURPOSE:To perform magnetic shielding surely without making a very low-temperature vessel large-sized and heavy-weight by providing a superconductive material layer for magnetic shielding on the surface of an inside tank of the very low-temperature vessel where principal elements are stored. CONSTITUTION:A very low-temperature vessel 1 consists of an insidetank 2, an outside tank 3, a vacuum heat-insulating layer 4 formed between these inside and outside tanks 2 and 3, and a superconductive material layer 5 provided on the inside face of the inside tank 2. A computer main body 6 is immersed in liquid helium P and is stored in the vessel 1. Constituting elements of the body 6 are constituted by gathering chips where Josephson junction elements are used as logic elements and most of signal lines are constituted with superconductors. Since the layer 5 is directly brought into contact with the helium P in this constitution, it is transferred to superconductors antomatically. Consequently, the layer 5 is allowed to fulfill well the function as a magnetic shielding body. In this case, the vessel 1 is not made large-sized and heavy-weight because no hindrance is placed even if the thickness of the layer 5 is reduced sufficiently.

Title: Automatic tuning circuit
Inventor: KAMIYA MASANORI
IPC: H04N5/44
Filed: 1978-07-26
Abstract: PURPOSE: To secure an accurate tuning with a simple constitution by controlling the tuning voltage via the presence or absence of the syncrhonous signal plus the output signal of the frequency discrimination circuit of the video carrier signal.  
     CONSTITUTION: With push of channel selection button 27, flip-flop 21 is set along with flip-flop 22 reset each. And the output of NOR circuit 17 becomes 1 to actuate constant current circuit 25. As a result, capacitor 24 is charged to raise up the  tuning voltage. When channel selection button 28 is pressed, the tuning voltage  lowers down. The tuning voltage is controlled by frequency discrimination circuit  12 to be raised up or lowered down automatically, thus obtaining the correct tuning  point. Synchronous signal decision circuit 13 is set by the presence or absence of the  synchronous signal. The synchronous signal is obtained usually only at the correct  tuning point, and accordingly the erroneous tuning to the aural signal can be prevented. As a result, the accurate turning is secured to the video signal.
